Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, and more specifically, to a high-efficiency hoisting device. Background Art

[0002] Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements. There are cargo holds inside the ship. When in use, batches of goods are placed in the cargo hold for easy transportation. After the ship docks, the cargo in the cargo hold is usually lifted using the crane at the port terminal.

[0003] In the prior art, for example, the Chinese utility model patent with publication number CN220684482U discloses a ship cargo loading and lifting device, which reduces the force generated by the swing of the wire rope by setting a fixed plate, a sliding plate, a buffer pad, a first spring and a damper, thereby achieving the purpose of reducing the amplitude of the cargo swinging in the air, and timely discovers the abnormal amplitude of the cargo shaking by setting a contact point, a contact, a controller and a buzzer, thereby avoiding a greater accident and achieving the purpose of improving the safety during lifting. However, the above technical solution still has the following defects: since the hook can usually only lift one piece of cargo at a time, the lifting efficiency is low, and increasing the number of lifting equipment will significantly increase the cost. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model proposes a high-efficiency lifting device, which can lift multiple pieces of cargo at a time through the cooperation of a lifting frame, a lifting rope, a hook and other structures, thereby filling a whole flatbed truck at a time, greatly improving the lifting efficiency.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a high-efficiency lifting device, including a lifting frame, an upper lifting ear, a steel wire rope, a lower lifting ear, a lifting rope and a hook. The lifting frame is a rectangular frame, and upper lifting ears are symmetrically arranged at both ends of the top of the lifting frame, the upper lifting ears are connected to the steel wire rope, and the free ends of the steel wire rope are connected to one place, and two rows of lower lifting ears are arranged along the length direction at the bottom of the lifting frame, the lower lifting ears are connected to the lifting rope, and the free ends of the lifting rope are connected to the hook; the upper lifting ears and the lower lifting ears are detachably connected to the lifting frame; and the bottom of the lifting frame is also provided with supporting legs.

[0007] In a preferred technical solution of the utility model, reinforcing ribs are arranged on the inner side of the hanging frame.

[0008] In a preferred technical solution of the utility model, the two rows of lifting ropes are connected by pull ropes, and the number of pull ropes matches the number of lifting ropes in each row.

[0009] The beneficial effects of the utility model are:

[0010] The utility model proposes a high-efficiency lifting device, which can lift multiple pieces of cargo at one time through the cooperation of a lifting frame, a lifting rope, a hook and other structures, so as to fill a whole flatbed trailer at one time, which greatly improves the lifting efficiency. The distance between the front and rear rows of lifting ropes matches the width of the flatbed trailer, so that the cargo can be evenly placed on the flatbed trailer, which helps to prevent the trailer from shifting its center of gravity and causing rollover.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] like Figure 1-3As shown, an efficient lifting device is provided in the embodiment, including a lifting frame 1, an upper lifting ear 2, a steel wire rope 3, a lower lifting ear 4, a lifting rope 5 and a hook 6. The lifting frame 1 is a rectangular frame, and the upper lifting ears 2 are symmetrically arranged at both ends of the top of the lifting frame 1. The upper lifting ears 2 are connected to the steel wire rope 3, and the free ends of the steel wire rope 3 are connected to one place. Two rows of lower lifting ears 4 are arranged at the bottom of the lifting frame 1 along the length direction, and the lower lifting ears 4 are connected to the lifting rope 5, and the free ends of the lifting rope 5 are connected to the hook 6. In this embodiment, the lifting frame 1 is made of a hollow square tube, which can minimize the initial weight of the lifting frame 1, thereby improving the lifting capacity of the equipment. The upper lifting ear 2 and the lower lifting ear 3 are both circular ring structures, and the upper lifting ear 2 and the lower lifting ear 3 can rotate in a vertical plane. The buckle at the bottom end of the steel wire rope 3 is buckled and fixed with the upper lifting ear 2, and the buckle at the top of the lifting rope 5 is buckled and fixed with the lower lifting ear 4. There are four upper lifting lugs 2, and the number of lower lifting lugs 4 in each row is equal and equidistantly arranged to ensure that the force on the lifting frame 1 is balanced. The positions of the two rows of lower lifting lugs 3 correspond one to one along the width direction of the lifting frame 1, and the distance between the front and rear rows of lifting ropes 5 should match the width of the flatbed trailer, so that the vehicle can be fully loaded at one time. The hook 6 is provided to lift the cargo when the lifting frame 1 is lifted.

[0018] Specifically, a reinforcing rib 7 is provided inside the hanging frame 1. In this embodiment, more than two reinforcing ribs 7 are provided, and the provided reinforcing ribs 7 can increase the maximum bearing capacity of the hanging frame 1.

[0019] Specifically, the two rows of lifting ropes 5 are connected by a draw rope 8, and the number of the draw ropes 8 matches the number of each row of lifting ropes 5. In this embodiment, the draw rope 8 is used to connect and fix the front and rear rows of lifting ropes 5 to reduce the shaking of the goods and improve the stability of the lifting process.

[0020] Specifically, the upper lifting lugs 2 and the lower lifting lugs 4 are detachably connected to the hoisting frame 1. In this embodiment, the number of the upper lifting lugs 2 and the lower lifting lugs 4 can be set according to actual needs to adapt to the hoisting of goods of different sizes and weights.

[0021] Specifically, support legs 9 are further provided at the bottom of the hanging frame 1 .

[0022] Working principle: When in use, the staff first sets the number of hooks 6 according to the size of the goods, and hangs the goods on the hooks 6, then the tower crane lifts the lifting frame 1, and then drives the goods to be lifted synchronously and loaded onto the flatbed trailer, so as to realize lifting multiple goods at a time, greatly improving the loading efficiency.
